Despite widespread use of the bacille Calmette-Guérin (BCG) vaccine, tuberculosis (TB) remains a leading cause of global mortality from a single infectious agent (Mycobacterium tuberculosis or Mtb). Here, over two independent Mtb challenge studies, we demonstrate that subcutaneous vaccination of rhesus macaques (RMs) with rhesus cytomegalovirus vectors encoding Mtb antigen inserts (hereafter referred to as RhCMV/TB)-which elicit and maintain highly effector-differentiated, circulating and tissue-resident Mtb-specific CD4+ and CD8+ memory T cell responses-can reduce the overall (pulmonary and extrapulmonary) extent of Mtb infection and disease by 68%, as compared to that in unvaccinated controls, after intrabronchial challenge with the Erdman strain of Mtb at ∼1 year after the first vaccination...

Tuberculosis (TB) is a common cause of morbidity and mortality worldwide and its eradication in the United States has stalled for the first time in decades. Isolated hepatic TB is an extremely uncommon form of extrapulmonary TB. Here we present a case of a tuberculous liver abscess and suggest that TB should be considered in patients who fail to respond to antibiotics and prompt diagnostic intervention.

Tubercular lymphadenitis (TBLA) contributes to 30-40% of extrapulmonary TB cases in the immunocompetent individuals and 40-50% in people with HIV. Current diagnostic methods for TBLA like Gene-Xpert or PCR are costly and conventional methods like fine needle aspiration cytology, histopathology lack sensitivity and specificity. Culture which is considered as gold standard require high turnaround time. Loop mediated isothermal amplification (LAMP) assay has been developed as a novel technique for nucleic acid amplification and has shown promising results in the diagnosis of pulmonary tuberculosis...

Tuberculosis (TB) of the head and neck region is quite common in endemic countries, but is still misdiagnosed due to its varied presentation and different sites of involvement. The aims of the present study were to present the diversities of presentation of head and neck tuberculosis with the diagnostic predicaments faced during evaluation and to assess treatment response to anti-tubercular treatment (ATT). We analysed 48 patients with head and neck tuberculosis who presented to the Department of Otorhinolaryngology in our tertiary care urban hospital over a period of two years from 2013 to 2015 and recorded their data, which included presenting complaints, local and systemic examination findings, investigation results and treatment outcomes...

Lung transplantation (LuTx) is an important treatment for a selected group of patients in the terminal stage of a number of lung diseases, which can bring them a significant improvement in quality of life and long-term survival. Nowadays a perioperative period is not significant limitation for patient survival due to the development of transplant surgery, but the period of months to years after LuTx is crucial for survival. The post-transplant period is very complicated for LuTx patients due to a special treatment regimen, special medication, especially immunosuppressive drugs and the possibility of many complications, whether early or late or acute or chronic...

Sarcoidosis is a systemic disease of unknown etiology, characterized by the presence of granulomatous inflammation in affected tissues. In about 90 % it affects the lungs, but it may basically affect any organ, the most frequently the skin, lymph nodes and eyes. In the case of classic lung manifestation this disease is not difficult to diagnose. When dealing with extrapulmonary manifestations, interdisciplinary cooperation is necessary. The treatment of sarcoidosis is needed in about half of the cases, in some 30 % of patients it may change into a chronic stage and possibly lead to serious health problems or premature death...

Nosocomial infections are a common complication of hospital care. Hospital-acquired (HAP) pneumonia is one of the most common nosocomial infections and it is the most dangerous in terms of mortality. The problem is mainly selected hospital bacterial strains with rising antibiotic resistance. Diagnosis of the cause of pneumonia is difficult and often does not lead to a positive result. Management is complex and is based on timely and appropriate empirical antibiotic treatment. Local and extrapulmonary complications are relatively common and they increase morbidity and mortality...

Strongyloides stercoralis infection is a common and neglected public health problem in many areas of the world. Here we report the case of a 21-year-old woman who emigrated from Cambodia to Japan and presented with swelling of the right supraclavicular region of 2 months' duration. She had no other symptoms. Tuberculous lymphadenitis was diagnosed based on a fine-needle aspiration biopsy of the right supraclavicular lymph node. The laboratory examination revealed mild eosinophilia (eosinophils 1348/µL).S. stercoralis and Hymenolepis nana were detected serologically and in faeces examination...

Elena Bargagli, Antje Prasse
Sarcoidosis is a systemic granulomatous lung disease of unknown origin affecting people of any age, mainly young adults. The disease is extremely heterogeneous with an unpredictable clinical course. Different phenotypes have been identified: an acute syndrome can be distinguished from subacute and chronic variants. About 20% of patients are chronically progressive and may develop lung fibrosis. Sarcoidosis usually involves the lungs and thoracic lymph nodes, although the skin, eyes, bones, liver, spleen, heart, upper respiratory tract and nervous system can also be affected...

Tuberculosis is a serious infection that is increasing in prevalence, affecting many people worldwide. The diagnosis of cutaneous tuberculosis is challenging and requires the correlation of clinical findings with often inconclusive diagnostic testing. Extrapulmonary tuberculosis comprises approximately 10% of all cases of tuberculosis, and cutaneous tuberculosis makes up only a small proportion of these cases. Discussed here is the case of a 61-year-old immunocompetent female with a large cutaneous lesion on her index finger secondary to Mycobacterium tuberculosis Tissue cultures taken at biopsy were negative; however, empiric antimycobacterial therapy was initiated...
